LYMAN D. HOlVARD, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE CLARK-HOWARD EXCAVATOR JERSEY.

AND CONVEYOR COMPANY, OF NEW ELEVATOR-BUCKET.

SPECIFICATION forming part of Letters Patent No 413,060, dated October 15, 1889.

Application filed March 15, 1339.

To aZZ whom it may concern:

Be it known that I, LYMAN D. HOWARD, a citizen of the United States, residing in the cityand county of Philadelphia, State of Penn sylvania, have invented a new and useful Improvement in ElevatorJ-Suckets, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of an elevator-bucket which is divided diagonally or obliquely and provided with means for closing the divisions or sections, as will be hereinafter set forth.

Figure 1 represents a side elevation of an elevator-bucket embodying my invention.

I 5 Fig. 2 represents a bottom plan thereof. Fig. 3 represents a side elevation of a detached portion on an enlarged scale. Fig. 4 represents a bucket embodying my invention with its sections separated, as in the position of discharging its contents.

Similar letters of reference indicate corresponding parts in the four figures.

Referring to the drawings, A designates an elevator-bucket, which is formed of suitable 2 5 metal and divided in an oblique or diagonal direction from top to bottom by the line B, forming the sections G D. The section D is hinged, as at E, to a band or strap F, which is connected with the top of the section 0, the

latter section being pivoted at its upper end to the chains, as at G. The lower portion of the section 0 is connected with the chains by means of pivoted links H,whereby the bucket may be thrown or turned outwardly when so 3 5 required to an extent limited by said links.

Pivoted to the bottom of the section 0 are catches J, whose noses engage with said bottom, and are held thus by means of springs K, which are connected with the supports of 0 said catches and bear upward against the lat ter. Rising from the catches .1, back of the pivots or axes thereof, are arms L, which are adapted to engage with shoulders M, depend ing from the bottom of the sections D. It

will be seen that when the catches are in their normal positions the sections of the buckets are held by the noses and arms of said catches, and thus prevented from. separatin The catches are extended rearward, form- Serial No. 303,384. (No model.)

ing arms N, which are adapted to strike a cross-bar or abutment P on the frame of the elevator, said frame also carrying a roller or abutment Q,which is located above said abutment P and so disposed that when the bucket rises its upper inner corner strikes said abutment Q, thus tilt-ing the bucket so that its lower end is set outwardly, in which position the arms N strike the abutment P, whereby the arms L clear the shoulders M, thus disconnecting the sections 0 D and permitting 6o them to open or separate, thus discharging the load at the bottom of the bucket.

The section C is pivoted between its center and front to the chain, so that the heaviest part of said section is at top, back of its axis. Consequently the bottom of the section is thrown outward, while the section D, being heavier at bottom, is thrown rearward, and thus the bucket separates or opens to a considerable extent.

As the bucket passes over the upper wheel of the elevator its position is reversed, and the preponderance of weight of the section D, which assists in opening the two sections 0 and D, will also assist in the closing operation. A closing check or abutment R may be so placed on the elevator as to cause said closing operation and force the section D in position and lock the latching mechanism.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is

1. A bucket formed in sect-ions and provided with a catch which has a nose engaging with one section and an arm engaging with a shoulder of the other section, substantially as described.

2. A bucket formed in sections and provided with a catch for locking the sections, in combination with abutments, one of which serves to tilt the bucket outward and the other to operate the catch for disconnecting the sec tions, substantially as described.

An elevator bucket consisting of ob liquely-connected sections, one of which is pivotally connected to a ring secured to the other, the band-section having a pivoted-link connection at its lower part with the bucketchain, said parts being combined substantially as described.

4. An elevator-bucket consisting oftwo sections pivotally connected and a catch con nected to one of said sections and having an arm adapted to engage a shoulder on the other section, and provided with a rearwardly-extending arm adapted to trip said catch, said parts being combined substantially as described.

5. An elevator-bucket consisting of two sections, one having a band to which the other section is pivoted, and a bucket-chain to which the band-sect ion is directly pivoted at its up per part and pivotally connected by a link near its lower part, and a catch connected to the band-section and having an arm engaging the pivot-section, and provided with a rear- Wardly-projecting arm adapted to trip said catch and release the sections, said parts be- 26 i'ng combined substantially as described.
